	Yersinia pestis (Site not responding. Last check: 2007-10-20)
		Yersinia pestis, the bubonic plague bacterium, is an R-form which has a genetic defect in the biosynthesis of complete lipopolysaccharide (LPS) and it lacks O-specific chains (Bruneteau and Minkab, 2003).
		Yersinia pestis may remain viable for months to years at freezing temperatures and may furthermore be viable in dry sputum, flea feces and buried bodies (Website 16).
		Yersinia pestis loses its protective capsule while in the gut of the flea due to the lower flea body temperature, therefore when it is injected into human tissue by the flea, the bacteria are easily phagocytosed by polymorphonuclear leukocytes (PMNs) and monocytes.

		The picture drawn by Holtz from her high-throughput data shows Y. pestis to be even tougher than suspected under conditions that mimic its life outside the human host, and possibly less vulnerable under human infection conditions to antibiotics currently used to treat plague, such as kanamycin, doxycycline and tetracycline.

		We first demonstrated that MST allowed biovar genotyping of a large collection of Y. pestis isolates and further applied it to the dental pulp collected from persons whose deaths are attributed to the first and second pandemics.
		We generated a list of Y. pestis CO92 intergenic sequences of 50 to 300 bp and carried out BLASTN searches to identify the homologous intergenic sequences in Y. pestis KIM strain by using the Y. pestis CO92 genes flanking the intergenic sequences as queries (13).
